farolero VS ulisp

You can use this library to get CL-style conditions and restarts in Clojure: https://github.com/IGJoshua/farolero

True, the CL REPL is more useful than the Clojure REPL, but CL has a 20-30 year head start in development. Plus, Clojure was developed as a hosted language, and runs on .NET, Javascript, JVM, and even Dart (in-progress).

Since exceptions are quite deeply integrated into those platforms (as opposed to conditions), it has "bled through" to the Clojure APIs, and, in turn, REPL.

Folks have written a CL-style condition/restart library for Clojure (https://github.com/IGJoshua/farolero) too.

conditions/restarts are also a possibility https://github.com/IGJoshua/farolero

Someone added conditions/restarts to Clojure: https://github.com/IGJoshua/farolero

It does allow errors to be caught by the Repl and just.hkw to handle them.

This is interesting tool[1] that allows much the same with Clojure

https://github.com/IGJoshua/farolero This uses derive hierarchies to enable general error handling.

I love his projects too. He's also the creator of uLisp.

Not CL, but there is ulisp (http://www.ulisp.com/) for microcontrollers, supposed to be really tiny, and there is Carp (https://github.com/carp-lang/Carp) which is without a GC so seems suitable for real-time stuff.

There's also ulisp (for Arduino projects etc.): http://www.ulisp.com/

This is larger, because there are functions for accessing peripherals, and the core is more standard lispy with 'caadr' et.al., and it has a compacting GC, so images can be saved as a compact blob.

You might consider uLisp, it's very Common Lispy for the memory constraints given (sans macros and splicing quote). And you can still connect to it and save an image. I've tried it and it works well enough. Here is the homepage.

Agreed - the interactivity is good. Lisp is close (have you seen http://www.ulisp.com/ - I can't believe they got into into that small a target!). Python is ok, but for some reason I don't use the REPL in the same way I do in Forth - I think calling functions is just harder somehow. Mostly is exploring valves from the Python REPL.
